When a freebsd32 caller uses all or most allowed space for control messages (MCLBYTES == 2K) then the message may no longer fit when the messages are padded for 64-bit alignment. Historically we've just shrugged and said there is no ABI guarantee. We ran into this on CheriBSD where a capsicumized 64-bit nm would fail when called with more than 64 files. Fix this by not gratutiously capping size of mbuf data we'll allocate to MCLBYTES and let m_get2 allocate up to MJUMPAGESIZE (4K or larger). Instead of hard-coding a length check, let m_get2 do it and check for a NULL return.
